function Leadtools.Annotations.Automation.AnnAutomation.paste()
Use the CanPaste property to determine whether annotation objects are in the clipboard and can be pasted. Use this property to update the user interface of your application (for example, enabling or disabling an Edit/Paste menu item). Call the PasteAt and PasteStringAt methods to actually copy the objects from the clipboard to this AnnAutomation.
Since clipboard operations is platform-specific, this method will use AnnPlatformCallbacks.GetClipboardData of AnnAutomationManager.PlatformCallbacks to perform the paste operation.
Note that the DeserializeObjectError event will fire if an error occur during the paste operation.
